(CNET) -- We still don't know if the Dell Streak is a tablet or a smartphone, and the new pricing for the device may confuse matters even further.

Dell's touchscreen tablet will go on sale Friday in the UK at retailer The Carphone Warehouse for €429, or $630.

But if you opt to buy it with a monthly data plan, you can get the Android device for free, the retailer announced Tuesday. The lowest plan is €25 -- or about $37 -- per month for mobile broadband access. You can also pay €35 ($51) per month and get voice and unlimited data.

That does seem like an appealing deal for a new touchscreen tablet. Compared to the iPad, where you purchase the device first and then can choose to buy a $15 a month 250MB data plan, or unlimited data for $30 a month.

But there's also a big difference: you can't use the iPad as a phone. The Dell Streak does allow voice calls.

It's made it difficult to pinpoint exactly how to categorize the Streak. Is it a smartphone? It is, after all, on the small side for a tablet (5-inches), runs Android like many other smartphones, allows voice calls, and is being sold through a wireless service provider. Dell, however, insists on calling it a tablet.

The Streak doesn't come to the U.S. until later this summer. Dell hasn't said whether it will be sold through a carrier stateside yet.
